Brief Summary:
To determine
The prevalence of abnormalities of femoral and acetabular versions and tibial torsion in symptomatic FAI Syndrome
Analyse the subgroups of specific hip pathomorphologies associated with rotational abnormalities of lower limb LL
Which specific hip subtypes of FAI are associated with rotational abnormalities
Outcomes of arthroscopic treatment of FAI syndrome in patients with rotational abnormalities compared with a control group of patients with normal rotation

Detailed Description:
Femoroacetabular impingement FAI is characterised by an abnormal contact between the acetabulum and the femur limiting range of motion and leading to hip pain and disability
FAI can be classified into three categories according to the specific pathomorphology involved Cam type FAI represents asphericity of the femoral head due to abnormal morphology at the head neck junction Pincer-type FAI on the other hand occurs due to over-coverage of the femoral head by the acetabulum and premature contact between the acetabulum and femoral neck Some patients may present with both of these abnormalities known as mixed-typed FAI
There is an interest in the role of acetabular and femoral versions and tibial torsion in FAI Lerch et al found that 68 of 538 hips presenting with FAI or dysplasia showed abnormal femoral andor acetabular versions A more recent study by Lerch et al also found abnormal tibial torsion in 42 of patients with FAI and dysplasia It has been further speculated that excessive femoral anteversion or femoral retroversion may also play a role in the pathogenesis and treatment of FAI Excessive femoral retroversion has been considered by some to be a relative contraindication to corrective FAI surgery as it has been found to be a risk factor for poor outcomes after hip arthroscopy for FAI Similarly increased femoral version is a risk factor for inferior clinical outcomes after hip arthroscopy Abnormalities of femoral version and tibial torsion were associated with anterior knee pain knee osteoarthritis and patellar instability But the influence of combined abnormalities of femoral version and tibial torsion combined torsional malalignment for patients with hip pain is unknown
So investigator hypothesized that patients with symptomatic FAI display significant rotation abnormalities of the acetabulum or femur and tibial and that the rotational abnormalities would portend an inferior prognosis when compared with a pair-matched control group of patients with normal range of lower limb rotation and patients with significant rotational abnormalities would have differing intraoperative hip pathology
